RESILIENT WHEEL.

Application filed January 13, 1914.

1o pensive construction.

More particularly, it is my object to provide such a wheel having an inner rim in the form of a channel with its side walls made of sections pivoted at their inner ends and operatively connected with an outer channel shaped rim in such a way as to permit movement of the outer rim vertically with relation to the inner rim but to prevent creeping thereof, the outer and inner rims being connected by yielding devices.

My invention consists in certain details, in the construction, combination and arrangement of t-he various parts of the device, whereby the objects contemplated are attained, as hereinafter more fully set forth,

pointed out in my claims and illustrated in the accompanying drawing, in which:

Figure 1 shows a side e evation of a portion of a rim embodying my invention. Fie.

2 shows a longitudinal, central, sectional view of a portion of said rim, taken on the line 2 2 of Fie. 2, and Fig. 3 shows a. transverse sectional view of said rim, taken on the line 3 3 of Fig. 2.

In the accompanying drawings I have used the reference numeral 10 to indicate `generally the body of the inner' rim which is in the form of a flat rim having outwardly extending flanges 11, at its edges and is pro- 40 vided on its under surface with sockets 12 to receive the outer ends of the spokes 13. Pivoted to the flanges 11 and extending outwardly therefrom are a plurality of segmental sect-ions 1d and 15. The sect-ions 14k rest against the flanges 11 and are pivoted thereto by means of bolts 1G and are spaced apart from each other in succession circumferentially around the inner rim. Sections 15 are also pivoted by means of bolts 16 to the flanges 11 which are arranged inside the rim. The lugs or pins 17 of the successive Specification of Letters Patent.

sections let are slightly spaced from the intermediate sections 15 when all the sections are in their normal position to allow slight play of said sections 15.

The outer rim. of my resilient wheel comprises a flat rim 1S having secured to its side edges inwardly extending llanges 19 overlapping the segmental sections lfl and 15, as shown in Fig. 'lhe llanges 1S) are detachably mounted on the rim 1Sby means of bolts 2O and are made in sections or segments, as shown in lfig. 1. In each of the sections lll is a slot 21 extending from its outer edge inwardly on radial lines. The [lange sections 19 are provided with pins 22 which extend into and travel in the slot 21. The rim 18 provided on its outer surface with spaced lugs 23 and is covered with a cushion tire 2-l-. The lugs 23 prevent the tire 211 from creeping. Mounted between the rim members l() and '1S are a plurality of powerful coil springs 25.

ln the practical operation of my improved resilient wheel, the arrangement of the segments or sections lll and 15, pivoted at their inner ends to the flanges 11 and mounted on the outer rim by means of the pins 22, permits the outer rim to move with relation to the inner rim to permit free resilient movement. At the same time the lugs 17 prevent any substantial creeping of the rims with relation to each other.

It will be seen that my improved wheel has a number of advantages, as shown in the last paragraph and as seen from the foregoing description. The arrangement is such that mud or pebbles will not readily get between the rim members while at the same time the outer and inner rims allow free play with relation to each other.

Many changes may be made in the details of the construction of my device without departing from its essential features and it is my object to cover by this application any such changes which may be included within the scope of the appended claims.

I claim as my invention:

1. ln a wheel of the class described, an inner rim, a plurality of segmental flange members pivoted to the outer edges thereof, and extending outwardly, each flange member being arranged to overlap the two adj acent flange members, lugs on each alternate flange member designed to engage the flange members on each side thereof, overlapped by the liange member carrying the lugs and arranged to limit the pivotal movement of said flange members, a channel shaped outer rim having sides receiving said segmental flange members and provided with pins mounted in and arranged to slide radially in part ot' said segmental lange members, and resilient devices between said rims.

2. ln a wheel of the class described, an inner rim having outwardly extending flanges at each side, segmental plates pivot ed to said lianges, the plates on each side of said rim being arranged to overlap eaeh other so that each segmental plate overlaps the two plates nearest to it, means on each alternate plate for engaging the two adjacent plates and limiting the pivotal movement thereof, part of said plates being provided with radial slots in their outer edges, a Channel shaped rim having its sides reeeiving said segmental plates, pins .extendinfr inwardly from said sides and arranged to travel in said slots, and resilient means for connecting the two rims to each other.

8. ln a wheel of the Class described, an 25 inner rim having outwardly extending flanges at each side, segmental plates pivoted to said flanges, the plates on each side of said rim being arranged to overlap each other so that each segmental plate overlaps 30 the two plates nearest to it, means on eaoh alternate plate for engaging the two adjacent plates and limiting the pivotal movenient thereof, some of said plates being provided with radial slots in their outer edges, 35

a Channel shaped rim Comprising a flat band, detachable flanges at each side thereof receiving the segmental plates on the first rim and designed to slide thereon, part of the plates or' said first rim being provided 40 Copies of this patent may be obtained for ve cents each, by addressing the Commissioner of Patents,
